SPlNNlNG lVlULE.

SPECIFICATION forming part of Letters Patent No. 388,054, dated August 21, 1888.

Application filed April 13, 1887. Serial No. 234,704. (No model.)

To all wit-0m it may concern;

Be it known that we, WILLIAM N. KIMBALL, of Bradford, and WALTER H. HERsEY, of IIaverhill, citizens of the United States, both in the county of Essex and State of Massachusetts, have in vented a new and useful Improve rnent in Spinning-Mules, ofwhich the following is a specification.

In certain grades of work in spinning yarns it becomes necessary to twist the warp one way and the filling-yarn in the reverse direc- I tion in order to obtain the best results in the appearance of the cloth. In the present method of doing this it becomes necessary to change each spindle-band, and, as there are from three to five hundred spindles to a mule, the time employed in changing the bands, which neces sitatcs the stoppage of the mules, renders it a tedious and expensive operation.

The object of our invention is to enable the spindles to rotate in either direction as required without the necessity of changing the spindle-bands, thereby effecting a great sav ing of time and labor, as well as wear and tear of the bands.

Our invention is illustrated in the accompanying drawings, in which Figure 1 is a top or plan view of the main shaft of a n1ule-carriage and mechanism embodying our invention for rotatingthespindles in either direction. Fig. 2 isa horizontal section through the same. Fig. 3 is a transverse vertical section through a mule and carriage, showing our device applied to the mule-earriage.

a is the main shaft provided at each end with the couplings u 2;, that carry the bandcylinder. On the main shaft a is fitted a sleeve, 8, carrying the faller mechanism (Z c f, the winding-gear 0, and clutches b b. On the shaft 0. is also mounted the gear in, and a gear, p, is mounted upon the sleeve .9.

Inside the mule-carriage is mounted an ad ditional shaft, h, which carries the rim-pulley g and cogwheel k, which are both fast on the shaft 72., and also a cog-wheel, 73, which is held by a feather and groove on the shaft, so that it is free to be moved in and out of gear with the cog wheel m on shaft a, and when in the desired position it is secured by a set-screw,i Ihe cog-wheel k on shaft h is always in communication with the cog-wheel p on sleeve 8 through the intermediate gear, 0. When the shafts a and it are to rotate in the same direction, the gears 70 0 1), being in connectiomtransmit motion from shaft h to sleeve 8, and the sleeve is secured to the shaft (t by means of a pin, t,passing through the sleeve and the shaft. When this is the case, the gear t on shaft 7?, is moved along said shaft out of connection with the gear at, as shown in Fig. 1.

\Vhen the shafts a and h are to be rotated in opposite directions,the pin if is drawn out from the sleeve 8 and shaft a, which allows the sleeve to turn loosely on the shaft, and the gear 1 is moved on shaft It, so as to be in connection with the gear on, as shown in Fig. 2, so that the sleeve 8 is rotated in one direction, while the shaft a is rotated in the opposite di' rection.

The spindles X (see Fig. 3) are driven by means of bands 3 passing over the cylinders .2, connected with the couplings u and o, and motion is imparted to the shaft h by the band qpassing over the rim-pulley g in the ordinary manner.

By the means above described it will be seen that the shaft a may be driven in the same or in the opposite direction to the shaft h, as required, and the necessity of changing the spindle-bands for reversing the motion of the spindles is dispensed with.

What we claim as our invention is- 1. The shaft a, provided with the gear in, in combination with the shaft h, provided with the adjustable gear 2' and gear in, the intermediate gear, 0, gear 19, the sleeve 8, and pint, substantially as shown and described.

2. The sleeve 8, provided with gear 1), in combination with the shaft or, provided with gear m, the pin 15, the shaft it, provided with adjustable gear 2', band-pulley g, and gear 6, and the intermediate gear, 0, substantially as and for the purposes set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
